Abstract: A receiving end of an electronic device includes an analog front end (AFE) circuit, a phase detector (PD), and a calculation circuit. The AFE circuit receives an input signal and adjusts the phase of the input signal according to a phase control signal. The PD detects the phase of the input signal to generate a current phase value and a phase difference accumulated value, calculates a target phase value according to the phase difference accumulated value, and generates a first phase driving value according to the target phase value and the current phase value. The calculation circuit generates the phase control signal according to the first phase driving value and a phase threshold. After the calculation circuit generates the phase control signal, the phase detector generates a second phase driving value, and the calculation circuit updates the phase threshold according to the first and second phase driving values.
